Abstract (en)
[origin: WO2010039395A2] The invention provides an orthodontic composition, related methods and packaged articles that include a hardenable component, a hardener, and a heat-modified inorganic mineral filler. The composition displays improved hardened remnant cleanup compared with compositions using traditional hard mineral fillers, while maintaining acceptable handling, bond strength and mechanical properties. Bond strength enhancement is achieved by heat-modifying a soft mineral filler, a process by which water of hydration is eliminated from the microstructure of the mineral to form a non-hydrated phase. By using heat-modified mineral fillers that are soft relative to human enamel, the hardened orthodontic composition can be conveniently removed using a low-speed abrasive disk or other mild abrasion process that is safer and more comfortable for the patient. The composition is especially beneficial for use in bonding orthodontic appliances to teeth.
